The extent of axial solid mixing could be well characterized with a diffusion model and a global mixing index under various experimental conditions such as excess air velocities, size differences of particles and concentrations of resins. It was found that a certain extent of mixing or segregation was reached after 90 s. Axial diffusion coefficients are varing from 1 to 5 cm2/s in this experimental ranges. The best conditions to incinerate anion resin beads with glass beads as bed materials in the gas-solid fluidized bed system, were 30 wt% of resins in overall composition and excess air velocity over 8 cm/s with glass beads having an averaged diameter of 320 μm.
